raw_atomic_long_or(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so this is the raw_atomic_long_or(9) page from the Kernel API Manual — it’s the atomic bitwise OR with relaxed ordering, and it’s here to update your long without the extra ordering drama. slay.

✨ SYNOPSIS ✨

void raw_atomic_long_or (long i , atomic_long_t *v );

🎀 ARGUMENTS 🎀

  • i — a long value. that’s the value getting OR’d in, bestie.
  • v — pointer to atomic_long_t. this is the atomic long that gets updated.

🦋 DESCRIPTION 🦋

Atomically updates v to (v | i) with relaxed ordering. literally the whole plot.

It’s safe to use in noinstr code; the page says to prefer atomic_long_or elsewhere. so like, if you’re not in noinstr land, use the other one — not a suggestion to ignore, fr fr.

⭐ RETURN ⭐

Nothing. void. no return value, no little treat, no crumbs. 💀
